Mechanical implementation of Pulse Width Modulation for dimming a light
A light that simulates Pulse Width Modulation (PWM) mechanically. Exploring ways to articulate the concepts of digital electronics, this is a light that you can alter the brightness of. Turning the handle adjusts the number of paddles that block the phototransistor. It is equivalent to a 16 position scale, or 4-bit grayscale.
